A fun and easy-to-use app that allows you to have fun lining up dominoes and making them topple over.

There are two play modes available: "Easy Mode, and "Edit and Test Mode."

*Easy Mode

A dynamic mode that gives you a diagonal view from the top.
When you drag the stage, the dominoes are lined up and then they will start toppling over at the same time.
Tap on the stage to make a ball appear.

Depending on how you touch the screen, you can line up an infinite number of dominoes from far away to up close, giving you enough options to keep you entertained.

*Edit and Test Mode

This mode gives you a view straight from the top. Though it features a fairly simple design, it allows you to build whatever you like.

Drag on the stage to line up the dominoes.
The bottom right of the screen shows an item palette. Drag on an item from this palette to place it on the stage.
You can combine dominoes and items from the palette to create a long line of toppling dominoes as you have never imagined before.
Once the stage is ready, press the "Start Experiment" button on the top right. This will topple the first light blue colored domino.

So, are the dominoes toppling just as you had imagined they would?

If you encounter a problem, that's absolutely fine. Press the "Stop Experiment" button and the dominoes will go back to their original positions.
Then you can add some more dominoes, or use the "Back" button to delete any dominoes that have already been placed.

*In some old devices, if you place a lot of dominoes, the screen may become slow and unresponsive. In this case, press the "Clear" button to delete the dominoes.
*We recommend using new models that have more processing power.

I think you apps are beautiful and so great for children however, these ads that come up are way too scary or too mature for children to see. Some of these are ads about demonic things, like the Movie “it”. Is too much for children. This is why i had to delete the apps from your company from all the devices my son was playing with. I looked to see if i could buy it so there wont be any ads however, there is no choice. Ads will be there no matter what. If i is ouls have to purchase the app, I WOULD IN A HEART BIT!!! But unfortunately thats not the situation. Thank you for making such great apps. My son and I loved them. If you do have them without ads please somehow let your customers know. Im pretty sure we all would buy these cute apps.

It’s Okay

I’m a experienced domino builder myself and using this has not helped me at all. It’s not even 3D! It’s just the top view of the dominoes. All you can see is the top and the face when it falls. I do like the objects that you can use but I’m not a big fan of the dominoes.
